In order to select the best liquid level sensor, we need to understand not only the characteristics and state of the liquid to be measured, but also the advantages and limitations of different detection methods, so as to be able to select the most suitable sensor. Here are some of the most common detection technologies on the market today. ...

Capacitive sensors have the advantages of simple structure, high temperature resistance, radiation resistance, high resolution, and good dynamic response characteristics, and are widely used in the measurement of pressure, displacement, acceleration, thickness, vibration, liquid level, etc. However, it is necessary to pay attention to the following aspects in the application of the influence on the measurement results: ...

Load cells can be wired in two different input and output ways: One is the four-wire connection method The load cell of the four-wire connection method has no special requirements for the secondary instrument panel, and the time and time of use are very convenient, but when the cable is long, it is very simple to be affected by the working temperature.

Sensor calibration refers to the process of transmitting the standard value expressed by the norm to the indexing of the sensor's operating range, and the indexing is determined. The calibration of the sensor is based on the standard value generated by a standard device (e.g. a known standard force, pressure, torque, displacement, etc.).

1. If the electronic ruler has been used for a long time, and the seal is now aged, and there are many impurities mixed with it, and the water mixture and oil will seriously affect the contact resistance of the brush, which will make the displayed numbers keep jumping. At this time, it can be said that the electronic ...

There are not many single ferrule terminal joints on the market now, and most manufacturers are using double ferrule terminal joints, and the market price is about 9-18 yuan, and the price is different according to different types. Fittings, whether double ferrule end fittings or single ferrule end fittings, are all selected.

Sensors we all know, at the same time the market demand is very large, there are many varieties, during which people are more commonly used light sensors and photoelectric sensors, although only a word difference, but the difference between the two is very large. 1. Different definitions: ...

1. The output working voltage of the proximity switch is selected, usually DC type DC24V or AC AC250V optional; 2. Proximity switch output mode selection, usually NPN-normally open, NPN-normally closed, PNP-normally open, PNP-normally closed, 2-wire normally open, 2-wire normally closed, DC 3-wire, DC 4-wire ...

The use of magnetostrictive elastic displacement sensors in industrial and consumer electronics is not small, and its marketed products are gradually used in metallurgy, aviation, wood processing, petroleum, industrial vehicles, bridge monitoring and other fields. The principle of magnetostrictive displacement sensor technology is to use two different magnetic fields to ...

1. Classification according to the way of engraving the disc is different (1) Incremental type: that is, every time the angle of the unit is emitted, a pulse signal is emitted (there is also a sine and cosine signal, and then it is subdivided, and the pulse with a higher frequency is chopped), usually the output of phase A, phase B, phase Z, phase A and phase B are ...

The premise of load cell replacement is that the axis of the applied force coincides with the axis of the sensor, we should know one thing, that is, with the increase of the additional load, the microvolt/indexing signal output by the sensor decreases. About the electromechanical junction of the S-shaped sensor installed in the second force transmission link ...

Vibrating load cell: When an elastic element is subjected to a force, its natural vibration frequency is proportional to the square root of the force. By measuring the change in the natural frequency, the force of the analyte acting on the elastic element can be calculated, and then its mass can be found. There are two types of vibrating sensors: vibrating wire type and tuning fork type. ...

Unlike load cells or force transducers, the measuring body of a torque transducer is not subjected to a tension load during operation, but is affected by the lever torque or torque, which can be changed. Therefore, torque sensors require special strain gauges to measure this type of load, i.e. torque. Canon...

Because the metal material is used as the elastomer of the load cell load cell, when the fine particles between the external force and the micro-strain disappear, the micro-strain disappears, but whether it can be fully recovered to the original non-stress state will be changed according to the metal data of the elastomer. ...

A load cell is a kind of sensor that converts physical quantities into electrical signal output, and is mainly used to measure the pressure or tension of an object. Its internal structure mainly consists of the following parts: 1. Elastomeric Element: Usually made of metal ...

Torque sensor is a sensor widely used in the mechanical category, which can measure the torque of rotating objects, and torque sensors have a wide range of application scenarios, and several typical application scenarios will be introduced below. First of all, the short-term sensor is widely used in the automotive industry to measure the engine and transmission.

The accelerometer is a sensor that can measure acceleration, this sensor can help the product to understand the environment in time, and it is very accurate, so what is the structure of its sensitive core? 1. Compression method: ...

An encoder is a device that compiles or converts signals or data into signals that can be communicated, transmitted, and stored. The encoder converts angular or linear displacement into an electrical signal. Fault Symptom: 1. The encoder itself ...

In recent years, the use of torque sensors has gradually increased, it can convert physical changes into accurate electrical signals, so what methods can torque sensors go through? The proven test method of torque sensors is ...

Resistive strain gauges, elastomers, and detection circuits are the first and foremost parts of the equation. An elastomer is a special shaped structure. It has two functions, firstly, it bears the load of the force on the cell and the external force, to achieve a relatively static equilibrium, and secondly, it ...

1. The safety barrier should be installed in a safe place, and the environmental conditions meet the requirements of the "application conditions" in the "Safety Gate Selection Sample". 2. The connecting wires of the intrinsically safe end (blue end) and non-intrinsically safe end circuits of the barrier safety barrier should be laid separately in the wiring slot.
